"If this is what women have to deal with in days or weeks or years of working in restaurants, or wherever they're working, then I can't even really imagine that, actually. It's kind of tough," said busser and server James Tilden.

The men lasted only an hour or two in the heels, which ran the gamut from red stilettos to cheap, black, strappy numbers.

But aside from the physical pain, they also described feeling vulnerable and uncomfortable as they worked.

A CBC camera caught Tilden's butt and chest being groped and poked. Co-owner Ivan Gedz described being grabbed by people he knew on the way downstairs — they quickly piped down when they realized Gedz was wearing a microphone, he said. And sometimes, joking customers went a little too far.

Servers discuss how the night went5:02

'Being stared at a lot'

"I walked downstairs, and it was a couple people we know in the industry and I won't use their names. They shut up pretty quick when they realized I was [wearing a microphone], but they kind of grabbed me or whatnot ... and I was like dude, do you get what we're [doing]?" Gedz said.

"Guys were making comments, jokingly of course, because that's what we were going for — to show light to it — but even those jokes that they were making were, after a while, still very uncomfortable to be faced with," said Tristan Bragaglia-Murdock, who was also serving on Wednesday.

Tilden said he eventually wanted to stop serving one particularly rowdy table.

"I went there if I had to, but kind of avoided it," he said. "I asked [another server] to take [a drink to them], and that was because I was like, OK, I could deal with this again, and I know it's joking and I was joking with them the first time, but at that point, I just didn't really want to deal with it.... It was annoying, and I just wanted to give them the drink and walk away, but I realized that wasn't going to be an option."

"I feel like this isn't exactly what it's like for women, however I feel like I'm put on the spot. I feel like I'm being stared at a lot. Obviously people are kind of smiling and smirking about it, but I feel like I'm on the spot and kind of the centre of attention," Tilden said.

'No need for a sexualized costume'

Co-owner Matt Fantin said the heels hurt him so much he couldn't function normally.

"After 45 minutes to an hour of wearing the heels, the pain I was in, I just had no focus for what needed to be done. And I would purposely make decisions contrary to what I would have in my right mind. I would see something on a table and be like, I can't turn around and fix that, so that's just going to have to stay how it is. Nowhere close to my normal level of service," he said.

Among the customers at Union Local 613 Wednesday were a few women who say they've experienced or witnessed sex discrimination at restaurants.

Kelly Reid has worked for restaurant chains including Jack Astor's, Boston Pizza, Red Lobster and East Side Mario's, as well as independent restaurants. She said sex discrimination was particularly bad at the chains.

"Their kind of corporate line that they would give is, look like you're going to the party, not coming home from the party. So I did witness a girl get sent home [from Jack Astor's] because she wasn't wearing any makeup. They said you need to have at least mascara on before you can work," Reid said.

"I've worked in the industry for a long time, and there is absolutely no need for a sexualized costume when it comes to women."

'Reinforces how ridiculous it is'

Jennifer Hatchard, who worked at a Jack Astor's in Toronto in July 2014 and said she quit after being sent home for not wearing enough jewelry on shift, was also at Union Wednesday night.

"I came here tonight because I love the idea of reversing sexist dress codes required in some restaurants to male colleagues. Seeing them wearing heels and short skirts is really something. I wanted to come down and be a part of it," she said.

"It reinforces how ridiculous it is. Seeing men walk by in tight miniskirts and heels really just hits it home how crazy it is to ask women to do that."

At the end of the day, Gedz said it's about choice.

"If a woman chooses to dress like this, she's made that choice and she's going to feel comfortable doing it. I guess I've made this choice to a degree, but I wouldn't be making this choice tomorrow. I can tell you that," he said.
